NOZZLE FOR SHEET-METAL CONTAINERS.

Application filed Ianuary.17, 1925. Serial No. 3,108.

This invention relates generally to metallic cans or containers and more particularly to the nozzle portion thereof.

While the invention is particularly adapted for use in connection with cans or containers for oils it will of course be understood that its use is not to be. restricted to containers for oil but can be used in connection with containers intended forany and all liquids.

It has been found difficult to pour oil in a steady even stream through the nozzle of the container, particularly at the start for the reason that the cohesive force orviscosity of the oil is such that in a large number of instances the discharge opening of the nozzle or spout is completely closed and the entrance of air for venting is entirely prevented.

-,Various forms of venting devices have been devised but in the majorityofcases these de vices are practically of "such construction as to interfere with the cheap and rapid production of the can or container and are furthermore expensive to construct and apply to the can. a 1

The object of this invention is to provide a venting nozzle in connection with a can, the construction of the nozzle and of the can being such that no additional costs will be added to the can proper and the construction 30 of the nozzle itself and the attachment thereto will be exceedingly small.

Another object of the invention is to provide a venting nozzle which can be quickly and easily applied to any and all types of flat top cans and usable in connection with any and all types of closures.

Another object is to provide a venting nozzle in which a portion-of the top of the can. will serve as a baflle plate to hold back the oil in order to permit the entrance of air for venting pur oses.

\Vith these an various other objects which will become apparent as the description proceeds,theinvention consists broadly in providing a discharge opening and a vent open ing in the top of the can and in making the nozzle with a vent opening having an area greater than the discharge opening or openings in the top of the can and providing this nozzle with a skirt attached to the top of the can and enveloping both the discharge and vent openings in the top of the can, said discharge and vent openings being so positioned that as the liquid passes through the discharge opening and through the nozzle air will pass through the nozzle beneath the skirt and through the vent opening in the top of the can. i

The invention consists also in certain details of construction all of which will be fully described and set forth in the appended claim.

In the drawings forming a part of this spec fication Fig. 1 is a side view of a can provldcd with my improved type of nozzle; Fig. 2 is a top plan view of the same; Fig. 3

is a vertical sectional view taken through the can and nozzle; F ig.'-l is a similar View showing a slight modification; Fig. 5 is a planview of the can top with the nozzle removed therct'rom; Fig. 6 is a vertical sectional view showing another type of nozzle and closure therefor; F ig; 7 is a modified form of top. 1 I

111 carrying out my invention I employ a can; or container A having a flat top I), thistop being united to the sides of the can or container in the usual or any approved manner and by having this top flat it can be readily usable in connection with the can assembling machine. Near the edge of the top Iprovide a discharge.opening'or openings C and adjacent the center of the can top I provide a vent opcning l). The nozzle E is preferablycircular in shape and can be of any suitable or desircd construction adapted .to receive any type of cap' or closure and in Fig. 3 I have shown an ordinary screw cap applied to the nozzle, whereas in Fig. (3 I have shown a nozzle to which a cap having a fastening lever is attached, said cap and nozzle being of the same construction as shown in thelVilliams Patent No. 1,3392%. The nozzle can be arranged at an angle projecting toward the side of the can as shown that the area of this opening (I is less than the mouth of the nozzle and by forming the opening in the shape indicated, that is with a rcentraut portion the liqu d when poured from the can will assume to a certain extent v the shape of the dischargeopening C and in so doing provide ample space for air to enter through the nozzle and pass under the skirt to the vent opening I). It 1s essential that the discharge opening in the top of the can should be so proportioned with reference to the opening of the nozzle that the oil or other liquid contents of the can when poured out of the can will not fill up the opening of the nozzle but will l ave space for air to enter and flow through the skirt to the vent opening D into the can. The vent opening D is to be positioned sulliciently remote from the discharge opening C that when pouring the contents out of the can, said contents will pass through the opening 0 and will not e11- tcr the vent opening D.

instead of having a single discharge opening C, I may provide a plurality of discharge openings 0 and in practice I prefer to so group these several openings 0 that as a whole they will provide a substantially crescent shaped perforate area the aggregate areas of the opening being less than the area of the discharge opening of the nozzle. By so proportioning the openings the top of the can acts in the nature of a ballle and holds back the oil or other contents so that a delinite quantity only passes through the discharge opening in the top of the can and through the nozzle and leaves sullicient space in the mouth of the nozzle to permit the entrance of the air which as before stated passes through the skirt and vent opening into the can and vents the same so that the oil or other contents flows freely through the discharge opening and nozzle.

Furthermore, by not only restricting the size of the area of the discharge opening in the top of the can but also imparting thereto the shape indicated or a substantially similar shape the pouring stream is given such a shape that the cohesive force of the liquid will be prevented from completely blocking the discharge mouth of the nozzle and a sullicient opening will be left along the opposite edges of the mouth of the nozzle to permit the free entry of the air into the nozzle and skirt connected thereto.

As previously stated, the nozzle can be made straight with reference to the can as most clearly shown in Figs. 3 and 6, or it can be arranged at an angle as most clearly shown in Fig. :l: but in both instances the discharge opening at the top of the can will be exactly the same and likewise the vent opening and the relative distances between the discharge and vent openings will be the same and likewise the relative relation between the areas of the discharge opening at the top of the can and the mouth of the nozzle.

by constructing the nozzle and skirt in the manner herein shown and described and using it in combination with the tint top can having the discharge and vent openings disposed as herein shown i am able to provide ample space for the discharge of the oil or other liquid and the entrance of the air without unduly increasing height ol? the nozzle and this is a very important factor in the storage of filled containers and particularly during transportation. leurthcrinore, the lilling of the can originally can be quickly and easily accomplished. The inclined spout is particularly advantageous inasmuch as it greatly facilitates the filling of the can originally and also renders the pouring operation much easier and enables a cleaner discharge and reduces to a minimum the slopping over of the contents as the pouring operation is suspended either suddenly or gradually.

It will thus be seen that I provide a simple, clijicient and practical nozzle in combination with a an top which is eomparatively inexpensive and easily attached to the top of the can, said top being of the standard.

size and shape and readily usable in connecting with automatic assembling machinery; and it will be further noted that the nozzle thus applied projects comparatively a short distance above the top of the can and therefore renders itself advantageous to the storage and transportation of the filled container.

Having thus described my invention, what I claim is A filling can of the class described having a discharge opening and a vent opening in its top wall, said discharge opening being substantially arcuate in shape, a nozzle secured to said top wall and embracing the discharge and vent openings, the aggregate areas of said discharge and vent openings being less than the area of the mouth of the nozzle whereby the liquid flowing through the discharge opening and mouth of the nozzle will assume a shape which will provide a space for the ingress of air through the nozzle and vent opening.

In testimony whereof, I hereunto ailix my signature.
